N6755A - 

The Keysight N6700 offers the ability to mix and match various performance level modules in a single mainframe package. The N6700 saves rack space for ATE applications with the smallest, highest density modular power supply available at only one rack unit high. The N6700 is also the fastest modular power supply for improving test system throughput.
If you need to deliver multiple channels of high power to your DUT, your job just got easier with the introduction of seven new highpower modules for the Keysight N6700 modular power system. The new modules expand your ability to customize the N6700 modular power system to meet your exact needs, even if you want to perform voltage and current measurements down to very low currents.
With four mainframes and over 30 DC power modules to choose from, you can customize the N6700 to meet the exact demands of your electronic device — from basic to precision, from 50 W to 1200 W. Get advanced features like built-in, scope-like digitizing measurements and power arbitrary waveform generation. No other power supply vendor comes close to matching the flexibility and capabilities of the N6700 modular power system family.
Features:

Mix and match 50, 100, 300 and 500 W programmable DC power modules in 400, 600 and 1200 W mainframes

Basic, high-performance (low ripple and noise, autoranging), precision (measurement), source/measure units (precision source & measure), and application-specific DC programma-ble power modules

List-mode/Power Arb, Sequencing, Built-in Digitizer; USB, GPIB, LAN/LXI-C Standard

Fast output changes (0 to 50 V in less than 2 ms) that are up to 50 times faster than other programmable power supplies

Advanced, fast digitized measurements that extend from milliamps to 50 amps

Autoranging output capabilities that enable one power supply to do the job of several traditional power supplies

High-speed test extensions that offer an oscilloscope — like digitizer that simplifies system configuration and increases measurement accuracy

With a single command, the ability to switch the output from a positive voltage to a negative voltage without changing wiring due to optional built-in polarity reversal relays
